Abstract
Kieselalge. Verdoppelung der Plastiden durch einfache Durchschnürung in der Interphase, starkes Streckungswachstum mit Kernwanderung unmittelbar vor der Zellteilung, typische Zentralspindel in der Anaphase, Beginn der Durchfurchung des Protoplasten in der Nähe des Kerns, Abscheidung je einer neuen Unterschale. Mit Zeitraffung.
The cells of the colony-forming Stephanopyxis turris multiply vegetatively by bi-division. The numerous lobed plastides double during the interphase by simple intersection. Cell division is initiated by marked longitudinal growth with migration of the nucleus to the equator of the cell. In the anaphase of the division of the nucleus the central spindle that is typical for diatoms appears. The fission of the protoplast starts near the nucleus. Cell division is completed with the secretion of a new lower sell for each of the two daughter cells.
